One of my teacher said Barron’s is bad. What are the best ones for Economics, English, and Biology?
Economics: I used Crash Course, but I’ve also heard Barron’s, 5 steps, and PR as good choices too.
English: personally I don’t think a prep book is necessary for either AP Eng test
Biology: Barron’s
Also, there isn’t really a “best” AP prep book publisher overall, you really have to go test by test, and the different prep books all have their own pros and cons.
